react and angular

Selecting the Javascript for your web application has become much more comfortable than earlier times with the top-notch tools. However, the final step deciding between the Angular or React is the toughest call you are going to make as a front-end web  developer. The Javascript landscape has been divided among these two most advanced frameworks, but most of the developers stuck when it comes to choosing between these two. Should I choose Angular or React? Is among the top most searched questions on the search engines. Whether you are an experienced developer looking for a tool to complete your organization's project or a newbie to the development seeking an informative and convenient start, the questions haunt them both.

So, what's the answer, how we are going to select the best one among these two? Honestly speaking we can’t decide which one is better, I can't tell you directly to choose to React or Angular. Moreover, neither the plenty of articles posted across the web around this debate can't help you this way. Both the frameworks hold different positions and help the developers in their own way. In order to know which one suits the best for your web app development, you need to thoroughly examine both the tools and know what they have to offer. Once you are aware of every ins and outs of Angular & React, you will be able to make the right decision on your own.

Without wasting any time let's get into the details of both the Javascript frameworks.

Difference between Angular and React?

Before moving towards the main components of the frameworks, you should know a significant difference between these two. Angular is a complete Javascript framework embedded with enormous features compared to React which is just a UI component library. So, it won't be fair to compare Angular with React, to take the fight on the common ground we consider the React connected to the other libraries that are commonly used only with it.

Some parameters to look before choosing a tool


Maturity is the scale to measure the popularity and success of any tool till date. Before opting for a tool, you must know how long it has been on the market. The tool is said to be mature if it has been used by a number of developers and showed no sign of a problem. The maturity of any tool could be due, because of a number of factors like being unstable or having bugs, maybe abandoned by the vendor, or perhaps not supported by a large community for help.


The second most important thing you should look for is what kind of features the tool offers. You need to compare them with others so you will know what variety of tools you have in your hand. Further, you must inspect that, are those features suitable according to the demand of your project?

How smooth is the learning curve?

There is no benefit of the feature-rich tool if you have to spend immense time and effort in learning it. The tool should come with a natural learning curve so the developers can easily understand it in no time for efficient results.

Here are some questions you should address before the decision.

  • Will be the framework going to exist here for long?

  • How responsive and helpful is the respective community with the tools?

  • Is it easy to find the developers for each framework?

  • On which basic programming concepts these frameworks works?

  • How easy is it to use the frameworks for small or large applications?

  • What kind of performance can you expect from the frameworks?

  • Where can you have a closer look under the hood?

  • How can you start developing with the chosen framework?

About Angular

Angular is one of the two mostly used javascript framework that is supported by Google. The framework is the successor of Angular JS which was turned down by Google after it has been accused of unnecessary complexity. So, the company took care of everything in the second version of Angular JS that is also used in Google Adwords and Google Fiber. This certainly clears how significant and essential Angular is for Google. Besides, Angular has some beneficial features like native app support.

Few reasons why should choose Angular

  1. The framework belongs to Google, so there is nothing to worry about.
  2. The codes in Angular are simpler to understand
  3. Comes with a simpler learning curve for the developers to adapt it without any issue.
  4. Apps based on Angular are interactive and customizable up to a great extent.

About React

React was introduced about five years ago and considered as the oldest Javascript framework for new generation. The framework is built and maintained by the social media platform Facebook, which also uses the framework in its product including WhatsApp and Instagram. However, React isn't an MVC framework instead it is an open source library for UI views only. The UIs built with the help of React is highly responsive and loads immediately.

Few reasons why You should choose React

  1. React is JS based library that comes with JSX compiler.

  2. Facebook supported the library and used for big products like WhatsApp.

  3. It is a flexible library with many benefits over other search engines

Features Offered by both the frameworks

Coming down to the features, Angular holds the upper hand in this field as its offers more features than React.

However, these benefit could both bad and good for a developer depending upon the developer’s point of view and project he/she working on.

Angular features

Here are some of the most useful features of Angular

  • Dependency Injections

  • Templates

  • Ajax request by angular/http

  • Routing

  • Component CSS encapsulation

  • XSS protection

  • Material Design Components

These beneficial features could help the developers in coming up with an intuitive web app. Besides, with all these features already present inside the tool, the developer doesn't need to waste their time in searching the libraries. However, in some ways this could be a problem as you are stuck with these features. Although you can replace them from the libraries, but it requires extra effort and time.

React top features

  • In React there aren't many features to look, here are all the library has to offer

  • XSS protection

  • Utilities for unit-testing protection

  • There are JXS and XML like language built instead of classic templates on top of Javascript

As mentioned earlier in React you won't find much inbuilt feature, which is good for the developers as they have the freedom to choose anything. The developers can do anything they want from the number of libraries in React. However, the developers need to do all the stuff by themselves in React including adding features from other libraries. Some of the popular libraries that are mostly used by the developers are React -router, Fetch for https requests, and Enzyme for unit testing utilities.

Core development

We already know that the tech giants support both Angular and React. Where Facebook uses React for WhatsApp and Instagram, and Google has implemented React in several projects including Adwords UI with Angular & Dart. Talking about the core development application of these frameworks we had a look at their Github popularity. Angular has more than 39033 stars and 690 contributors whereas React owns almost 107,618 stars and over 10,201 contributors on Github at the time of writing this article. So, it can be seen that the freedom of adding features from different libraries benefits React over Angular on Github.

Technical Comparison: Angular Vs. React

technical requirement


MVC (Model-View-Controller)

Breaking the entire data of the project or application into smaller and readable component, i.e., Model, View, and Controller helps the developers to write shorter codes for a better quality product. The MVC pattern allows the developers to do quality work with the required assistance. So, the MVC model along with the Model View Presenter and Model View-Viewmodel is still preferred by the developers. Angular is entirely based on MVC architecture, however, React supports only the View part of the MVC pattern.


Templating is one the most important feature that no developer wants to miss while working on a web application. While using a Javascript framework, you can't afford to skip on the templating options. Angular offers number templating options using Typescript files and React in JSX files for creating UI.

Data Binding

The data binding is one of the most important steps for building a web application as it establishes a relation between UI and the business logic of the app. To carry out the whole app’s process it requires the data binding in frameworks. Angular uses the two-way data binding approach in which it connects the DOM to Model data using Controller. However, the two-way approach hampers the performance as every binding has a watcher to spot the changes in DOM.

On the other hand, React uses one-way data approach for the data binding. In this, the data flows only in one direction that makes the work easier. With the one way approach, it is easier for the developers to debug the process having large applications.


The libraries and frameworks are divided into different categories using the license. Where some of them are flexible and allows the developers to adjust them according to the requirements, others don't. The flexible ones are known as the open-source products while others don't allow to make the commercial apps or change the content. Both React and Angular are the open source frameworks, that means you can make the changes accordingly as there is no restriction about commercial apps and usage. Angular comes under the MIT license and React falls under the 3-clause BSD.


Rendering in Javascript is known as the fetching data in order to make the app works efficiently. There are basically two ways of rendering in the frameworks it is either client-side rendering or server-side rendering. The client-side rendering affects negatively to the app as it slows down the page loading. The Angular JS has the client -side rendering, that is further resolved in its next iteration. Now, both Angular and React has server-side rendering process.

Important Information about React

React has a number of topics to talk about from a developer’s point of view, that includes


JSX is one of the most debatable points when it comes to React; some think it is a huge issue other finds its helpful. In React the JSX combines both makeup and logic within the components using the XML instead of following the classic approach with separated markup and logic. This allows the developers to write the markup directly into the Javascript. With this the developers get the benefit of static analysis, the JSX markup compiler will spot the errors as soon as you make it instead of letting you to continue with the error. It helps in rectifying the silly errors in time while writing the codes.


Flow is the type-checking tool for the framework developed by Facebook. The tool is capable of spotting the implicit errors and parsing the codes for the developers. Unlike TypeScript in Angular, Flow doesn't require you to get into a new language and annotate your code for type checking. In Flow, the annotation of the codes are optional, besides it provides the additional hints to the developers. Instead of overwriting the existing code, it suggests the change to the user with static analyzing.


Redux can be understand as the tool that developers take into action to make their life easier when things get real messy. Redux is used for the ’state of management’, that deals with the inner parts of the app. The tool is complicated and comes with steep learning curve. It is more about the inner look and feel of the web app and managing it requires Redux. The tool may be hard to understand for the designers but they need to learn it as it would help them in giving efficient performance. With the help of the tool developers can easily get to know the advantages and implications of the actions.

Important Information about  Angular

Angular also has some important and beneficial features under the hood that could help in taking the better decision.


The new generation language is built by Microsoft at the top of Javascript. This is the enhanced version of Javascript ES2015 that comes with more features inherited from the new language. The typing system in this language is robust and it analyze the codes with the help of various annotations and type inference. Moreover, the Typescript is also influenced by Java and .NET, so if you're familiar with these languages, then it will more manageable for you to learn Typescript over Javascript.


This is an exclusive Reactive library that enables the more flexible and customized handling of the operations. RxJS can be taken as the perfect blend of observer and iterator pattern along with the functional programming. With the help of RxJS, you can treat anything as the continuous stream of values in order to perform distinctive operations like mapping, filtering and much more.

One Framework for all?

Now, you knew that how much different these two frameworks are and you have the better idea in selecting the best one. You need to consider all the parameters and project requirements to choose the most suitable framework. Once you select the most prominent tech stack for the project, you will be tempted to use it in all upcoming projects. However, you don't need to blindly follow the same approach every time, although keeping the consistency is good, but before every project take your time to decide. Compare the cons and pros depending upon the requirements may be your landscape will be different next time. So, you need to examine both the frameworks and then decide which framework worths for your current project.
